Title: Japanese word data storing system
Inventor: TAKAGI TOMOHARU
IPC: G06F17/21
Filed: 1992-11-11
Abstract: PURPOSE:To increase the registering capacity of a floppy disk, etc., by storing the Japanese word data created by a Japanese word processor after compressing the data. CONSTITUTION:A control means 1 instructs a character string extracting means to extract a character string at the head of a document. The extracted character string and its length are sent to a retrieving means 3 which retrievers the same character string right after the extracted one. If the same character string is retrieved, this character string is registered into a common character string data entry means 4 as a record and the registered entry number is returned. The means 3 buries the entry number in place of the character string and fills a vacant part with a specific character. Thereafter the same processing is repeated until the end of the document. When the retrieving of a character string is through, the means 1 extracts again another character string out of the data following the first extracted character string. When the character string are extracted up to the end of a document, the retrieving action is through. Finally the special characters are excluded so that the document is compressed.
